WEST LAFAYETTE — Purdue University has uncorked a new online series examining Indiana's wine industry and all of the steps needed to produce a fine bottle of wine.

The new "Through the Grapevine" feature debuted Tuesday on the website of Purdue's "Agricultures" publication with a segment on four wine varieties, two red and two white, that are putting Indiana's vineyards on the wine-sipping map.

Series organizer Natalie van Hoose will draw on the expertise of Purdue's grape and wine specialists for a new segment each Tuesday about Indiana grapes. She says "Indiana's wine industry may be small, but it's really quite remarkable."

The series will also explore issues such as how rising temperatures have affected the range and varieties of grapes grown in Indiana.
